Process requiring energy are termed what?
Endergonic; if the energy is supplied in the form of heat, endothermic.
What is another name for light dependent reations of photosynthesis?
The exergonic reaction is a chemical reaction that releases energy (photosynthesis). The product of light dependant reactions is called endergonic reaction. It is a chemical reaction that requires energy.
What are three types of post-translational modification?
methylation lipidation glycosylation phosphorylation
What is the speed at which a reaction occurs called?
The chemical term is reaction rate.
What occurs at the cathode of a galvanic cell?
An oxidation half-reaction
The energy for an endergonic reaction comes from what kind of reaction?
The energy for an endergonic reaction can come from an exergonic reaction, where energy is released. This released energy is then used to drive the endergonic reaction forward.
An endergonic reaction that is driven by the splitting of ATP molecules?
In an endergonic reaction, the overall energy change is positive, requiring input of energy. By breaking down ATP molecules, which release energy, the energy released can drive the endergonic reaction forward. This coupling of the endergonic reaction with the exergonic ATP hydrolysis allows the endergonic reaction to proceed.
Why would it be beneficial to couple an exergonic reaction with an endergonic reaction?
Coupling an exergonic reaction with an endergonic reaction allows the energy released from the exergonic reaction to drive the endergonic reaction, making it energetically favorable. This coupling enables cells to carry out important processes that would not occur spontaneously due to their energy requirements.
Which portion of the pathway in Figure 9.1 involves an endergonic reaction?
The portion of the pathway in Figure 9.1 that involves an endergonic reaction is the uphill segments where energy is consumed or absorbed to drive the reaction forward. Endergonic reactions require an input of energy to proceed and are typically associated with the synthesis of molecules.
In cells what is the source of energy for an endergonic reaction?
In cells, the source of energy for an endergonic reaction is usually adenosine triphosphate (ATP). ATP provides the necessary energy molecule for the endergonic reactions to occur by transferring phosphate groups to molecules in order to drive the reaction forward.
Which of these reactions requires a net input of energy from its surroundings?
An endergonic reaction requires a net input of energy from its surroundings. This is because the energy needed to drive the reaction forward is greater than the energy released during the reaction.
Coupling occurs when the energy released by an exergonic reaction is?
captured and used to drive an endergonic reaction. This allows the energy released by one reaction to be harnessed and used to power a different reaction that would not occur spontaneously. Coupling reactions are essential for many biological processes that require energy input.
What is the differences between exothermic reaction and endergonic reaction?
exothermic reaction releases energy and endergonic reaction absorbs energy
When a cell uses chemical energy to perform work it couples a reaction with a reaction?
When a cell uses chemical energy to perform work, it couples an exergonic (energy-releasing) reaction with an endergonic (energy-requiring) reaction. This coupling allows the cell to harness the energy released from the exergonic reaction to drive the endergonic reaction, enabling the cell to perform work such as transport, mechanical movement, or synthesis of molecules.
What type of reaction is phosphoenolpyruvate ADP to Pyruvate ATP?
This reaction is a phosphorylation reaction where phosphoenolpyruvate transfers a phosphate group to ADP to form pyruvate and ATP. It is catalyzed by the enzyme pyruvate kinase, an important step in glycolysis for ATP production.
What is endergonic?
Endergonic refers to a chemical reaction or process that requires energy input to proceed. In these reactions, the products have more free energy than the reactants. An example of an endergonic process is photosynthesis.
Photosynthesis is an endergonic reaction. Why?
As opposed to an EX [as in expel] -ergonic chemical reaction, endergonic reactions absorb energy.
